Echocardiographic indicators such as atrioventricular valve index, right ventricle\/left ventricle inflow angle, and size of the ventricular septal defect have been identified as relevant discriminators that may guide surgical strategy. Our purpose is to describe another metric to refine surgical decision-making.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>We outline a geometrical description of the anatomic features of atrioventricular septal defect and describe equations that help explain the interplay between the main echocardiographic variables.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>A new metric called \u201cindexed ventricular septal defect\u201d is defined as the size of the defect in relation to the valve diameter. We derive a final equation relating this index with the atrioventricular valve index and the right ventricle\/left ventricle inflow angle. In the light of that equation, we discuss the interdependence of variables and employ data from a Congenital Heart Surgeons\u2019 Society study to set the limits of the new index.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Combined use of indexed ventricular septal defect and atrioventricular valve index might help clarify surgical decision-making in patients with mild and moderate unbalance (modified atrioventricular valve index between 0.2 and 0.39). For indexed ventricular septal defect smaller than 0.2, biventricular repair may be recommended. Between 0.2 and 0.35, this strategy could probably be achieved depending on other factors. However, other strategies should be considered for those patients showing an indexed ventricular septal defect between 0.35 and 0.5. For values above 0.5 to 0.55, univentricular palliation might be a reasonable strategy.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/2150135117716420","type":"journal-article","created":{"date-parts":[[2017,11,7]],"date-time":"2017-11-07T09:50:44Z","timestamp":1510048244000},"page":"460-467","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":12,"title":["Feasibility of Biventricular Repair in Right Dominant Unbalanced Atrioventricular Septal Defect: A New Echocardiographic Metric to Refine Surgical Decision-Making"],"prefix":"10.1177","volume":"8","author":[{"given":"Ignacio","family":"Lugones","sequence":"first","affiliation":[{"name":"Cardiac Surgery Unit, Children\u2019s Hospital Buenos Aires \u201cPedro de Elizalde,\u201d Buenos Aires, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda Fernanda","family":"Biancolini","sequence":"additional","affiliation":[{"name":"Cardiology Unit, Children\u2019s Hospital Buenos Aires \u201cPedro de Elizalde,\u201d Buenos Aires, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julio C\u00e9sar","family":"Biancolini","sequence":"additional","affiliation":[{"name":"Cardiology Unit, Children\u2019s Hospital Buenos Aires \u201cPedro de Elizalde,\u201d Buenos Aires, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana M.
